Blame and File History

Blame overlays each line in a file with the commit and author that last changed it. Use it to understand why a line looks the way it does, not just when it was introduced.

Opening blame

From any open file on the Code page, use View → Blame or the toolbar's blame toggle. The file re-renders with a blame gutter on the left, one entry per line showing commit hash (shortened), author, and relative timestamp.

Clicking a blame entry

Click any blame entry to open the full commit in the Diffs and Commits view: message, author, changed files, expandable per-file diffs. Handy for stepping through the history of a suspicious line.

Walking back through history

From the commit view you can jump to the commit's parent and re-blame the file at that revision. Repeat to trace a line back as far as you need.
